TH ROUG HWAY-TAP.

SPECIFICATION forming part of Letters Patent No. 683,087, datedSeptember 24:, 1901.

Serial No. 66,387. (No model.)

To all whom it may concern.-

Be it known that I, JAMES WESTLEY, brass founder, a subject of the Kingof Great Britain and Ireland, residing at 10 South View, Belvoir avenue,Levenshulme, in the county of Lancaster, England, have invented certainnew and useful Improvements in or Connected with Throughway-Taps, (forwhich I have made application in Great Britain, No. 8,661, dated April27, 1901,) of which the following is a specification.

My invention relates to throughway-taps used for controlling the supplyof water, steam, or other fluids, as is well understood, and hasreference to an improved method of packing such taps to prevent theescape of fluid.

In the accompanying drawings, Figure 1 shows in sectional elevation athroughwaytap constructed in accordance with myinvention. Fig. 2 is aplan, and Figs. 3 to 5 detail views.

According to my invention I provide a suitable valve-box A, having athroughway-plug a, which is preferably formed taper, and I incase theplug a with a tube'b of vulcanized rubber composition, asbestos, or ofany material suitable for packing purposes. The material from which thetube b is composed formsno part of my invention, and I mayem ploy anysuitable packing composition for the purpose which can be formed ormolded to the requisite shape. The packingtube b is formed with recessesc, engaging with corresponding lugs g, formed on the gland cl to preventthetube b from turning. The packing-tube b is formed with passages e forthe transmission of fluid, which passages I may line with metal, ifnecessary or desirable, to prevent undue wear upon the packing materialby the passage of the fluid. The gland d is arranged upon the top of thepacking-tube b and the throughway-plug a, and pressure being brought tobear by means of the gland through the screws fa fluid-tight joint isreadily made and maintained. In Fig. 1 the passage h ofthe pluga isturned so as to cut off supply. By means of a suitable handle engagingwith the squared end f of the plug ct 'the plug may be turned until thethroughway-passage it corresponds with the passages e in the tube 1).The tube 17, as stated, is pre-' vented from turning by means of theprojections or lugs g on the gland d, which engage with the recesses cof the tube b. In Fig. 3 I show a sectional elevation of the tube 11.Fig. 4 is an outside view at right angles to Fig. 3, and Fig. 5 is aplan. The packingtubes 19 may be easily molded to the requisite size andshape from suitable packing material or composition.

An important feature of my invention con sists in the ease with whichthe packing-tube b when worn out may be renewed, as on removal of thegland the plug a and packingtube 6 may be at once removed from the bodyof the valve and a new tube placed upon the plug a, which is thenreturned to the valvebox and the gland again screwed down. One glandonly is required, as the bottom of the valve box or chamber is closed.The upper is not flanged and the gland d by pressing thereon will adjustthe packing.

I declare that what I claim is-- In combination, the tap a and itscasing having a projection g, a packing having an upwardly-opening notchengaging said projection and having its upper edge plain and agland'bearing on said plain edge to adjust the packing, substantially asdescribed.

In witness whereof I have hereunto set my hand in presence of twowitnesses.
